Be it known that I, MILO BJSELTER, a

citizen of the United States and; a resident a part of this specification.

This a invention relates to an automatic stop mechanism for attachment upon talking or record playingf machines operating to apply a brake to'the record carrying disk of the machine after completion of the playing of a record, to hold the carrying disk against. the movement imparted thereto by the spring motor generally providedas an operating means. I I 7 The device embodies a number of novel features, particularly one whereby the stop.

7 As shown in the drawings: The casing of the playing machine is denoted a whole by the reference numeral 1, and is provided with a floor or horizontal partition 2, therein, rotatable above which and driven in any suitable manner is a horizontal flat record carrying disk on which a record is supported and rotated therewith, when played. A record 1,.is shown supported "upon a carrying disk 3, in Fig. 1, and mounted at one corner on the partition .wall or floor 2, is a. universally movable recorder arm 5, having a ball and socket connection 6, at the point of support upon a partition wall or floor 2, as-

cle arly shown in the enlarged view of Fig. 4. Secured upon the top surface of the partition 'wall or floor 2, at a point beneath the record carrying disk and near the periphery thereof as shown in Fig. 2, is a stationary plate 7, held securely in position by means of screwsS. Secured near one end of said plate 7, is a stud or pivot 9, and pivoted thereon and contacting the top surface of the stationary plate 7, is a brake arm 10, having a short extension 11, which has a fiber or insert of other material 12, adapted to contact with the inner peripheral surface of the downwardly turned flange of the carrying disk 3, as shown in Fig. 2. One edge of said brake arm 10, is flanged upwardly as denoted by the reference numeral 13, to afford a finger grip whereby the, brake arm may be thrust into. release position.

Formed integral with said brake arm 10,

and extending on the opposite side of the pivot 9, is a tail lever extension 11, having connected to the outer end thereof a spiral spring 15, which is in turn connected to the flanged end of a latch lever 16, pivoted on a stud 17, secured in said stationary plate. 7, at the end opposite from the stud 9. Said lever 16, is bent upwardly away from the stationary plate 7, as clearly shown in Fig. 5, and formed on the end thereof is a curved arm portion 18, as clearly shown in Fig. 7,

wnich is provided with a recess on its inner curved edge affording a shoulder 19, adapted to receive in latching engagement therewith,

a lug 20, projecting upwardly from the middle portion of the brake arm 10, clearly shown in Fig. 6. Pivotally mounted upon the stud 9, is a ring or collar 21, which lies flat against the top surface of the circular portion of the brake arm 10, and is provided with rounded projection 22, which is at all times engaged in a rounded complemental recess provided therefor in the outer curved end 18,.of the lever 16, as clearly shown in Fig. 7. Said collar or ring member 21, is provided with an upstanding tubular hub portion 28, which extends upwardly beneath the head of the pivot 9, and secured thereon flat above said ring or collar 21, is a fiat circular head of a release lever or arm 24, so that said release lever 2i, and said ring member 21, are constrained to pivot in fixed relation as a unit upon the pivot 9.

In order to hold the parts in assembled relation, a four-fingered spring element 25, is engaged over the hub extension 23, bearing downwardly upon the top surface of the flat circular head of the release lever 2i, and

is heldthrust downwardly by a pair of nuts 26, threaded on the upper end of the hub extension One edge of said stationary plate 7, is flanged upwardly as denoted by the reference numeral 27, and is slightly bent over the rounded head of the release lever 2%, as clearly shown in Figs. 2 and '6, and said flanged portion 27, is provided with a slot 28 through which the tail lever 14, extends so as to be limitedin its movement thereby. Said release lever or arm 24, has pivoted on the outer end thereof as clearly shown in Figs. 2 and 8, a slot-ted plate 29, having a slot 30, therein, said plate being normally. held in' upright position by a counterweight 31, formed integral with said plate, and also serving as a linger grip and mounted so that the plate 29, may be forced downwardly into the horizontal position shown.

A curved bracket member 32, is secured a pin 8-1 shown in detail in Fig.11, and

held securely in adjusted position in said arm by'a lock nut 85, also threaded on sa d pm. A. projection 36, is formed on the lower end of the pin 34:, for coaction with the slot 30, in the pivoted stop brake 29, at the end of the release lever The operation is as follows: Referring to Fig. 1, in playing the record a. the recordingv or reproducing arm of the talking machine swings inwardly from the outer periphery of the record toward the center thereof and it is then desirable to bring the driving mechanisms for the record to rest at the time thatrthelrecorder, ar reaches itsextremeinner position ofmove' either by the fingers or merely by theswing;

ingot the recordingarmb; outwardlyItoward the initial position for'playing where:

by the projection 20, on saidcbrakeiarm :10,

will look behind the shoulder 19, (shown in Fig. 7,) of the curved lever '16.-,-1S, thus holding said brake arm'outwardly with the brake insert 12, out of contact with the flanged periphery of the disk which carries the record. 1 A trial swing of the recorder arm 5, is then made inwardly tothe extreme inner position which the same will assume upon the completion of the playing of the record, but prior to such inward swinging movement of the recorder arm the counter-weight 31, on the release lever 24, is,

swung upwardly into the position shown in Fig. 3. Thus the projection 36, on the lower end of the pin which is attached to and moves with the recorder arm, engages in the slot 30, ofthe stop plate 29, so that the release arm 24, is caused to swing to one side as said trial inward swing of the recorder arm 5, is made. The recorder arm 5, is then elevated by movement of its ball and socket connection to withdraw the projection 36, from the slot 30, of the stop plate 29, whereupon the counterweight 31, swings downwardly, as shown in Fig. 4, and the recorder arm is then swung to the outer periphery of the record 4, to be played, so that the pin member 34, attached thereon, is in the position shown in F ig. 4.

When the record is played, the recorder arm is started at the outer periphery of the record 4, and travels inwardly toward the center of the record, and at the completion of the playing of the record, the pin member 34, attached on said recorder arm, strikes against the upstanding stop plate 30, thereby swinging the release lever 24, slightly to one side, and, owing to the fact that said release lever is connected upon the tubular hub extension 28, of the ring 21, the projection 22, on said ring, serves to swing the curved lever 1618, outwardly, so that the a shoulder 19, on said curved lever, is moved from behind the lug 20. This release of the.

lug 20, causes the stressed spring 15, to draw the tail lever extension '14, of the brake armlO, suddenly inwardly, so that the brake arm 10, is swung fromthe dotted line positiorilshown, 2, to the full line posi- V tioii,,;and thebrake insert 12,"is pressed firmly upon theinrier surface of the flange of the record carrying disk to bring said disk and its driving mechanisms to rest.

The inward pull, of the spring 15, uponthe ,tail lever 14', has no effect 'uponthe adjustment of the release lever mechanismfor the reason that the stress of said spring is transmitted through the lug 20, andfshoulder 19,

of-the curved arm16 18, substantially in line with the pivot center 17, thereof, and I the friction of the parts due to the four struction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose-limiting the patent granted other wise than necessitated by the prior art.

I claim as my invention:
